7. Rates of reactions Flashcards
1
Q
How do you measure the rate of reaction?
A
Rate of reaction = (Amount of reactant used) / (Time)
Rate of reaction = (Amount of product formed) / (Time)
2
Q
How doe s a chemical reaction occur?
A
When particles collide with sufficient energy (the minimum amount of energy require is called the activation energy)
3
Q
What increases the rate of reaction?
A
Temperature
Pressure (If a gas)
Concentration
Surface area
4
Q
What is the definition of a catalyst?
A
A catalyst is something that increase the rate of reaction without being used up
5
Q
Why are catalysts important in industry?
A
By increase the rate of reaction they decrease the cost of the production
